Apache will not start: Cannot find /usr/local/apache/bin/litespeed

Symptoms

Apache will not start after the Litespeed license expires, and an error similar to the following will be in the logs.

Sep 28 11:36:51 server.domain.tld restartsrv_httpd[1707233]: [ERROR] Cannot find /usr/local/apache/bin/litespeed

Description

This issue occurs when the LiteSpeed license expires while it is running, which prevents LiteSpreed from switching to Apache. Reinstalling the ea-apache24-config-runtime package corrects this issue.

Workaround

1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
2. Reinstall the ea-apache24-config-runtime package.
   • CentOS 7, CloudLinux 6/7

     yum reinstall -y ea-apache24-config-runtime

   • Almalinux 8/9, CloudLinux 8/9, Rocky Linux 8/9

     dnf reinstall -y ea-apache24-config-runtime

   • Ubuntu

     dpkg --purge --force-depends ea-apache24-config-runtime

     apt-get install ea-apache24-config-runtime

3. Switch the webserver to Apache.
